Thread: Some basic for loops I'm stuck on.

Sequences for n = 5:

1 2 6 12 20

1 2 6 24 120

1 4 9 16 25

100 50 200 100 400

2 5 8 11 14

1 3 6 10 15

1 1 2 3 5 8 13

0 2 6 12 20

20 22 18 24 16

0 1 3 7 15

I have to make it so it prints that, each on a new line, exactly like that.

How about working out what the sequence for each output is. Some are easier than others. Once you know the sequence, the Java code will follow.

I'm aware of the sequence for some, not all.
I'd post the code I have if I was at school at the moment.

That really doesn't help me. I realize what I'm supposed to do, but I can't figure out how to do it.

I'd post my code, but unfortunately I'm at school and can't access the necessary files for BlueJ on the school server. Thanks anyways.

        a = 1;
        int b = 1;
        for (int i = 1; i <= n; i++) //come back to this later
        {
            System.out.print(a + " ");
 
 
 
 
 
    }

There's my code. (For the first set of outputs)
